This puffy thrives in nasty weather. Our tester wore it as his outer layer in sleet, snow, cold rain, and lows down to 15°F, and he stayed warm and dry through it all. Credit goes to the stormworthy hood, 750-fill down, waterproof zippers, and eVent shell fabric.
“The comfort range is impressive,” said our tester. “Even when I was digging a snow cave, this jacket moved excess heat through before I started to sweat out.” A more affordable option: the $215 Pertex Microlight version (it’s just as warm but not waterproof). $400; 1 lb. 8 oz. (L); men’s S-XXL; us.rab.uk.com.
